Abstract

Turbine blade (1) comprises a profiled blade (2) extending along a blade axis (4) and on which is molded in an end region a platform (6) extending perpendicular to the blade axis. The platform has an outer edge (14) which is thicker than the platform base (12). The side wall (16) of the outer edge facing toward the blade axis is angled. A hook base (8) is molded over the platform on the end region of the blade. An Independent claim is also included for a casting system for producing the above turbine blade. Preferred Features: The outer edge of the platform is provided in its base region with a number of cooling bores (20) opening on the outlet side into a common cooling gap (22).
